As a Caps fan, I'll say that reports on Urbom make him the type of player that the Caps are in need of on the blueline. Prefaced with the fact I've never seen him play, Caps have a need for a steady, defensive-minded blueliner that has enough mobility + size in their own end to make things difficult for the opposition. Right now, Erskine is on the 2nd D pairing and while he provides a physical presence, he's shown time and again that his lack of footspeed keeps him from being able to shutdown anyone with decent quickness/agility.
Other than that, Mike Green and John Carlson are decidedly offensive dmen, with Alzner really being the only real "shutdown" dman. The 3rd pairing has been a revolving door with a bunch of guys that play hard, but none that are notable for their defensive abilities.
Urbom might not project to be more than a #5/#6, but that's what the Caps need. If that turns out to be accurate, I wouldn't say it's the end of the world that New Jersey lost him.
